They are a perennial plant that grows at sunny places such as slanting surfaces or in the pool of the forest and the roadside along the mountain stream. (Perennial plant takes several years to grow). The shape of the leaves is rounded, which is the reason they are named ‘Viola keiskei’ (Marubasumire). As they resemble much Viola hondoensis which also have rounded leaves, the leaves of Viola keiskei (Marubasumire) have sharp tip that is nearly heart-shaped. This is how to distinguish the two. The flower is about 2 cm in diameter and the flower petals are also rounded. The trichome grows a little at the root of the flower which blossom sideways, mainly in white but some have the back of the flower petals in dark red color. In many cases, they grow in cluster and show up very well even during the blossom season. Tubular nectary or spur (Kyo: a portion of outpunching behind the flower petal) is about 6 to 7 mm long and has purple patterns. The leaves are about 2 to 4 cm long during the blossom season, but the summer leaves grow to be large about 7 to 8 cm long, and the plant height itself gets taller till about 30 cm.
